Bulacan's Strategic LocationThe Province of Bulacan may very well be considered as one of the few provinces in the Philippines that greatly benefit from its geographic location.

The province boasts of its strategic location, which is equidistant with the northern and southern parts of Luzon.

At the same time, it is proximate and accessible to the National Capital Region (NCR) or Metro Manila where most of development impulses originate.

Bulacan is one of the seven provinces comprising the Central Luzon Region. It is bounded by the provinces of Aurora and Quezon on the east, Nueva Ecija on the north, Pampanga on the west and Rizal on the southeast and Manila Bay on the southwest.

Dubbed as the "Northern Gateway from Manila," it is in Bulacan where the national trunkline road, Philippine-Japan Friendship Highway, forks in the Cagayan Valley Region in the northeast and towards the rest of North Luzon in the north and northwest. Such accessibility is a key factor that prompted private investors to develop several industrial estates in the province.

Bulacan has also become an important link between the large and consolidated consumer market in Manila and the resource-rich provinces of North Luzon. The province's strategic location is further highlighted in Central Luzon's regional development as it is expected to play an important role in realizing the "W Growth strategy of the Medium Term Development Plan of the Region."

Today, Bulacan has positioned itself as a premier province not only in Central Luzon but also in the whole country. Its strategic location opens the province as an expansion area for industries. The province's rapid urbanization is attracting investment and economic activities.
